Title: Welding of curved metal sheets to make shell-like structures etc. - where longitudinal edges of sheets are bent to form reinforcing beads which also locate weld metal
Inventor: WEIKERT DIETER
IPC: B65D90/08
Filed: 1979-04-04

At least some of the sheets are bent in the longitudinal direction and possess longitudinal edges bent for form a bead with a round cross-section. A bead on two adjacent sheets is used to form a seam filled with weld metal on one or both sides of the joint. The average radius of curvature of the beads is pref. 2-3 times the sheet thickness; and the joints may be partly or completely filled with weld metal. The beaded edges forming the seam can be held together by clamping pliers. The beaded edges of the sheets provide the welded prod. with high rigidity.
Patent DE-2917323-A1 (DE)
Title: Charging circuit for reserve supply battery - has DC=DC converter charging battery at voltage higher than DC mains
IPC: H02J7/00
Filed: 1979-04-28
Abstract: The charging circuit has a dc/dc converter converting the dc mains voltage into a voltage suitable for charging the battery. The converter is switched on by an electronic switch when the dc mains voltage is present. A current limiter is connected after the battery and the voltage drop across it is roughly equal to the voltage by which the dc mains is increased by the converter. The advantage lies in the ability to use reserve batteries the voltage of which is equal to the dc mains voltage whilst at the same time ensuring that the voltage across the load is the same as that appearing when the dc mains is present.

Title: Radio intercom system using delta modulation - allows multi-user operation with minimised cross channel interference
Inventor: FIGOL GEORG DIPL ING
IPC: H04M9/02
Filed: 1979-05-17
Abstract: The ratio intercom system uses delta modulation techniques to allow use by a member of subscribers without interference. Each subscriber unit has a delta modulator and demodulator stage. In the transmission stage, a microphone delivers signals to a low pass filter and then to an adaptive asynchronous delta modulator stage. Two switches are controlled by +1 and -1 outputs from the modulator, to generate two carriers of frequency, f+ DELTA f/2 and f - DELTA f/2 from separate oscillators. The signals are transmitted to the output stage and the communication channel. The receiver has separate filter stages to identify the carriers. Rectifying, integrating and low pass filter stages complete the receiver.

Title: Fluid desensitised safe-arm detonator assembly - for oil well perforating gun assembly, involves rotation of housings to obtain necessary condition
Inventor: REGALBUTO JOHN ANTHONY
IPC: F42D1/04
Filed: 1979-07-06
Abstract: A detonating assembly comprises the housing members which are axially aligned with each other and have respective bores for a detonator and a booster. The housing members are movable about an axial shaft from a safe position with the bores non-aligned and an armed position in which the bores are aligned. A safety pin extends into a cut out portion in one of the housing members and covers one end of the booster bore when the housing members are rotated to a safe posn. Used as safe/arm detonator assembly for an oil well perforating gun. The gun assembly may be transported with the detonator assembly in the safe position and rotated to the armed position at the well site without disassembling the gun assembly. The safety pin covers and protects the booster from accidental detonation when the detonator assembly is in the safe position. The movement between safe and armed positions does not disturb the seal between the exterior and interior of the gun assembly so that the latter is protected from invasion of well bore fluids. The condition of the gun assembly is indicated visually.

Title: Solar heating system heat collector - is insulation block with water reservoir behind flat plate in contact with water circulating tubes
Inventor: WOBIG ALBERTO
IPC: F24S10/75
Filed: 1980-05-08
Abstract: The heat collector for a solar heating system, suitable for heating swimming bath water, has a triangular section body (18) made of an insulating material (19) with a recess in its longest side. Into the recess is fitted an aluminium absorber plate (16) about 2mm thick. In good heat contact with this plate are two longitudinal tubes (11,12) for the circulating water being heated by the solar radiation. Also incorporated inside the body, behind the plate, is a cylindrical recess (12) forming a reservoir for the water being heated. The tubes, which are made of stainless steel, have their ends bent over to fit inside the ends of the reservoir. The collectors can be designed so that the fluid circulates naturally, assisted by gravity.

Title: Protected-contact bench socket outlet - has U-shaped flexible earthing straps running centrally below plug entry recesses
Inventor: GREINER GEORG
IPC: H01R24/76
Filed: 1980-05-08
Abstract: The bench socket outlet consists of an insulated housing (2), with an upper and lower section (3,4). The upper section (3) having two plug entry openings (5), below which, are the contact sleeves. Between these, is a double strip, made up of two earthing strips (7), extending centrally beneath the plug entires (5) and formed from a crossbar, and four vertical contact blades (10). These contact blades (10) are fixed to the cross bar (8) by a 'U' shaped spring section made up of an upper and lower spring blade (11,12) and a spring bend (13), the free ends (20) protruding through openings (19) in the plug entry space (5), with a convex configuration. The 'U' shaped spring section affords a long pliant spring path and thereby, a certainty of good contact. In addition, metal fatigue is avoided by the use of the spring shape, and since the cross bar, spring section and contact blade (10) only require little space vertically to the mounting plane of the earthing strap, they are easily mounted inside the socket housing.

Title: 1,1,1,4-Tetra:chloro-2-hydroxy-4-methyl-pentane catalyst prodn. - by addn. of hydrogen chloride to 1,1,1-tri:chloro-2-hydroxy-4-methyl-3-or-4-pentene in the presence of water
Inventor: ZOCHE GUENTER DIPL CHEM DR
IPC: C07C29/62
Filed: 1980-06-24
Abstract: In a new process for the prodn. of 1,1,1,4-tetrachloro-2- hydroxy- 4-methyl-pentene (I), HCl is added to 1,1,1-trichloro -2- hydroxy-4-methyl-3-pentene (IIa) or 1,1,1-trichloro-2- hydroxy -4-methyl-4-pentene (IIb) in the presence of water. Also new is the use of (I) as a catalyst in the isomerisation of 1,1,1,-trichloro-2-hydroxy -4-methyl-4-pentene to 1,1,1-trichloro-2-hydroxy- 4-methyl-3-pentene. Conversion of (IIa,b) into (I) is pref. carried out with conc. aq. HCl or with gaseous HCl, pref. using a chlorinated hydrocarbon as solvent. The amt. of water present during the reaction may vary within wide limits, but must not be such that the HCl is present in the form of dilute hydrochloric acid. Addn. of HCl to (IIa,b) in the presence of water gives (I) in practically quantitative yield. Use of (I) as catalyst for thermal isomerisation of (IIa) to (IIb) gives a considerable redn. in reaction times (cf.DE3023488).
